Here's some: (IMHO) 1. Move the girl off-center (I been readin' up on composition). 2. Maybe something in the distant background? A lone tree or something? 3. What is that next to her? If it's water, it probably shouldn't have a shadow. 4. The position of the hand resting on the leg doesn't look natural. Question: What is she looking at? Should the audience be able to see it? Well, maybe not. That's it. Nice pic.
